Product Description
Material Description

With high melting point, high thermal conductivity, and high strength at high temperature and other characteristics, in particular, its good heat resistance, tungsten products becomes the critical part of quart furnace. Tungsten tube, tungsten material bench, tungsten core rod, and tungsten shaper are the four parts which are most critical to quartz smelting furnace.

Quartz has a melting point of 1750 degree celsius. In order to melt quartz, it requires containers with higher melting points. Tungsten products then become the best choice. Through our many years of joint research and development with our customers, we've tailored an optimum tool for the whole quartz industry to manufacture high quality quartz.


Areas of Application

The quartz production process uses continuous melting method, that is, it needs continuous melting of quartz without stopping. Thus each stop will add high cost to the enterprise. Repeated studies prove that the properties of tungsten materials can meet the demand for quartz continuous melting process; therefore the materials are widely applied to quartz melting furnaces.
